Abstract:
The problem with cavitation and possible pitting in internal combustion diesel engines is studied here. Both theoretical and numerical simulation studies are carried out in order to understand the noise and vibration sources using a force equation. Noise and vibration are modeled in both 2D and 3D using the finite element analysis software ANSYS. A model pressure variation is carried out using the software with finite element analysis and fluid – structure interaction analysis interface. Some relevant results have been shown with the presence of negative pressures leading to the realization that the models developed predicts the presence of cavitation in the cylinder liner surface, indicating that cavitation can occur.
